only a succession of feeble and often aimless actions manifesting an equal lack of dexterity in either hand. Where left-handedness is strongly developed, it is, on the contrary, not only accompanied with more than average dexterity in the organ thus specialised, but also with a command of the use of the right hand, acquired by education, which gives the individual an advantage over the great majority of right-handed men. The surprise occasionally manifested at any display of dexterity by left-handed performers, as though it were accomplished under unusual disadvantages, is altogether unjustified. In reality, a strongly developed left-handedness is, equally with a strongly developed right-handedness, an indication of exceptional dexterity. Such skill as that of the left-handed slingers of the tribe of Benjamin is in no way exceptional. All truly left-handed, as well as all truly right-handed persons, are more likely to be _dexterous_ than those who are unconscious of any strong impulse to the use of either hand. The bias, whether to the right or the left, is, I feel assured, the result of special organic aptitude. With the majority no well-defined bias betrays any unwonted power, and they merely follow in this, as in so much else, the practice of the predominant number. But there is no such difference between the two hands as to justify the extent to which, with the great majority, one is allowed to become a passive and nearly useless member. The left hand ought to be educated from the first no less than the right, instead of leaving its training to be effected, imperfectly and with great effort, in later life, to meet some felt necessity.
